Notes
Do you want a quick introduction to ELO rating in chess, how it is calculated, how can you understand your probabilities of winning vs another player and the points added or subtracted to your rating after each game? Here is a good starting point.
The methodology and statistical rationale can be used in other games (football, basket, etc…) to predict end results and defining probabilities.
Insightful one if you love to bet on sporting results and you like to play with statistics!
Enjoy!
